My first experiments with a partial capo!
One suggestion is to use it the "Wrong way round", so that it presses the D-G-B strings, second fret at the treble side, thereby giving true open A. Nice easy start, and I have a good selection of slides at the ready!
I have two other Shubb capo's C1 and C4, and this is up to the expected high standard of manufacture. The Gold/Brass finish is different, but should make it easier to identify this capo from the others.
